Description
Technical Field

Background
In the field of communication, most communication equipment needs air cooling for heat dissipation, and the heat dissipation method is that cold air flows through a heating part, the heating part transfers heat to air, and then the air takes away the heat. The typical structure of this heat dissipation method is shown in fig. 1, and is mainly divided into three major parts: the system comprises a fan, a temperature sensor and a main control. Wherein, the fan is responsible for driving wind power to flow; the temperature sensor is responsible for checking the temperature of each part to realize the temperature acquisition function; the master control is responsible for analyzing the temperature data and controlling the rotating speed of the fan.
The working process is as shown in fig. 2, when any sensor detects that the temperature is too high, the main control can adjust the speed of the fan to enable the fan to rotate quickly, so that more air volume is blown in and sucked out, more heat is taken away, and the purpose of cooling is achieved; when all sensors detect that the temperature is lower, the main control can adjust the speed of the fan, so that the fan slows down the rotation, the blowing-in and the suction of the air volume are reduced, the heat brought away by the air is reduced, and the purpose of heat preservation is achieved.
However, the method is a method of 'strong wind flood irrigation', no directionality exists, and the fan speed is increased due to overheating of any board card. Other boards which do not exceed the temperature are also cooled passively, so that the boards which are cooled passively cannot work at a proper working temperature, and the working efficiency is reduced. Therefore, a large amount of cold air is wasted, and the temperature adjusting effect is not good.
Because of customer's demand, not all trench of communication equipment will insert the integrated circuit board, have some trench vacant, and communication equipment on the market all let wind flow through every wind channel through the even messenger of fixed wind channel structure. Therefore, a lot of wind power resources are wasted, and only the wind flows away in vain without taking away heat.

Preferably, the air duct control device in the embodiment of the present invention is a damper, or a structure equivalent to the damper.
Preferably, the air duct control device is located at the air outlet of the air duct, but not limited to being arranged at the air outlet.
Preferably, the air duct control device is composed of two blocks: firstly, the circuit design for driving the motor to rotate and keep a specific rotation angle is adopted. The main control unit converts the acquired data of the temperature sensor into a corresponding air duct sectional area, namely an angle which is finally required to be rotated and maintained by the motor.

When the internal temperature of the equipment is higher than 25 ℃, whether the air door is opened for cooling treatment is judged according to the detected data of the temperature sensor at the specific clamping groove part.
Preferably, through the adjustment of the air duct control device, the main control unit dispatches the wind power resources which are originally distributed to all the slot positions evenly to the slot positions and the board cards which need to dissipate heat most by using a control distribution algorithm, so that the utilization efficiency of wind power is greatly improved.
